本手册旨在补充，而不是以任何方式取代各种ASTM试验方法，用于骨料和新拌硬化硅酸盐水泥混凝土的取样和测试。本手册由混凝土和混凝土骨料委员会C09编制，并已被协会接受，仅供参考。本手册不是ASTM方法的一部分。C09委员会欢迎对手册提出意见和建议。 许多骨料和混凝土规范基于ASTM测试方法的结果，因此严格遵守测试方法的要求很重要。不当使用测试程序可能会导致有关骨料和混凝土质量的数据不准确和错误结论。 因此，本手册将关注可能影响测试结果的许多因素。 本手册并非旨在解决与其使用相关的所有安全问题（如有）。这些标准的使用者有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

This manual is intended to supplement, not in any way to supersede, the various ASTM test methods for sampling and testing aggregate and freshly mixed and hardened portland-cement concrete. The manual was prepared by Committee C09 on Concrete and Concrete Aggregates and has been accepted by the Society for publication as information only. The manual is not a part of the ASTM methods. Comments and suggestions on the manual will be welcomed by Committee C09. Many specifications for aggregates and concrete are based on the results of ASTM methods of testing and therefore strict adherence to the requirements of the test methods is important. Improper use of test procedures can result in inaccurate data and mistaken conclusions about aggregate and concrete quality. Accordingly, this manual directs attention to many of the factors that might affect the results of the tests. This manual does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of these standards to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
